Lightning is one of these natural events that catch people’s imagination. In real world they can be linked to a disruptive electric discharge due to the dielectric breakdown of the air between the clouds or between the clouds and the ground.
The use of lightning protection systems are the most effective method of reducing the risk of fire, explosions and damage to infrastructure due to lightning.

Water is a fundamental utility. Its increased consumption is the reflection of population growth and an improved standard of living. A more efficient use of drinking water is growing in significance, especially against the backdrop of increasingly scarce drinking water resources. Therefore, waste water treatment plants are a key element of the drinking water cycle.
Due to vast surface areas and exposure of frequently isolated sites, water and wastewater treatment plants are...

Prior to export, processed crude oil is stored in Floating Roof Tanks (FRT) to further allow any trapped gas within the crude oil to escape, and further stabilise the oil. In the oil and gas industry, FRT’s are vital in the processing of crude oil to the acceptable export specification. However, because of global climate change, the frequency of accidents which include equipment damage and fire damage caused by lightnin...

Due to the increased risk when storing large amounts of crude oil and the relevant final products, special personal and environmental protection measures are required. Various regulations, describe measures that ensure safe operation of storage facilities with focus on fire protection measures. Since lightning constitutes an ignition source, suitable protection measures must be taken to reduce this hazard source to the...

Who needs a lightning protection system?
Every industry which has sufficient risk of a lightning related event causing harm and damage to a structure, the people in and around it and the systems on and within it requires a lightning protection systems.
How often does lightning strike?
Data from

Lightning is the leading known cause of storage tank fires and it’s a constant treat.
Though all industries are at a risk of lightning strikes; even areas with infrequent thunderstorms can experience rare, but high intensity lightning strikes, the Petrochemical industry has the most shared data in losses.
Problem:
Lightning on tank storage and energy sources can c...

Lightning strikes are characterised by very high stroke currents arriving in a very brief amount of time. This current will flow across the surface of the earth until the cell between the thundercloud and earth is neutralised. The current will flow in all directions, although the amount will vary in proportion to the path of lowest impedance.

Since the dawn of civilization, lightning has inflicted a great deal of damage on structures built by mankind. Over 100 years ago, an effective method of protection became available when Benjamin Franklin invented the lightning rod.
A lightning rod is a metal rod that sticks up from a roof that will carry the current from a lightning strike safely to ground. It is typically copper or aluminium today, although Ben...

Data center equipment is complex and sensitive. One of the key failure sources at data centers is voltage transients. One power surge can destroy or reduce the life span of the equipment. It may cause a significant amount of money to recover from any amount of downtime or hardware damage resulting from a surge.
The crucial functions of data centers must be safe guarded from power surges caused by unreliable power off the grid or by direct and indirect lightning strikes.

The terms surge protection device (SPD) and transient voltage surge suppressor (TVSS) are used to describe electrical devices typically installed in power distribution panels, process control systems, communications systems, and other heavy-duty industrial systems, for the purpose of protecting against electrical surges and spikes, including those caused by lightning.
Surge Protection Devices...
